Figure 3b. Results of computer-simulated RF heating. (a) Graph shows effect of background heating [{sigma}(O)] in siemens (S) per meter on T2cm for three different inner conductivities [{sigma}(I)]. (b) Graph shows radius of several isotherms generated around the inner compartment that had an inner conductivity of 1.7 siemen/m and demonstrates the distance at which various thermal isotherms can be found in relation to the midpoint of the RF electrode. Both T2cm and the isotherms follow a negative power function based on the inner and outer electrical conductivity.
